I wanted to take a moment and thank Armorpoxy for answering my questions and providing a great product. It turned out great. Now the downfall wait until I can park on it.
What worked best for us was to take small hand fulls and toss from waist height. Only a few spots got a bit clumpy.
One thing we did that seemed to help is one person used the spike shoes (highly recommended) and as soon as we finished rolling a section throw the flakes on. As it was still very wet they embedded in the epoxy quite well.
